PMQs: Harriet Harman as Winston Churchill?

Previous clashes between these two have rather disappointed some blood-thirsty observers: Ms Harman proved she's much tougher than many people realised, and Mr Hague has been a bit tentative for fear of looking like he's trying to beat up Labour's leading lady.

Today, he got it spot on, targetting both Ms Harman's absent boss and her open-secret desire for his job.

Urging Ms Harman to make a bid for No 10, Mr Hague taunted her with history: "When Chamberlain lost the confidence of his party, Churchill stepped in…"

The stony look on Ms Harman's face spoke volumes. She may have the thickest skin in modern politics, but even she can't enjoy being laughed at this much.
